General Principles



Differential Diagnosis



  • Pelvic mass


  • Cervical neoplasia


  • Prolapsed fallopian tube


  • Gartner duct cyst


  • Vaginal polyps


  • Vaginal adenosis


  • Vaginal endometriosis


Imaging and Other Diagnostics



  • Patients with abnormal vaginal bleeding require ultrasound imaging. Consider obtaining a CT scan if a pelvic mass is suspected.


  • Cervical cancer screening is required preoperatively.


Preoperative Planning



  • The route of surgery depends on the indication for trachelectomy, surgeon’s experience and comfort, the presence of comorbidities, and the need for concomitant procedures. The preoperative planning for a vaginal trachelectomy begins with a thorough history and physical examination. The surgeon should pay particular attention to the degree of prolapse, the presence of a pelvic mass, adnexal tenderness, and whether the cervix is mobile. A laparoscopic approach should be considered if the patient has unexplained pelvic pain or suspected endometriosis, or if there is an adnexal/pelvic mass requiring removal. Counseling should include the risk of conversion to laparotomy, independent of a minimally invasive approach.


  • Confirm the patient’s cervical cancer screening is up-to-date.


  • Patients with significant medical comorbidities should also undergo preoperative clearance.


  • Perform thorough counseling and discuss the risks, benefits, alternative, and different routes of surgery. Obtain a signed, informed consent.

Regardless of the surgical route, a trachelectomy is a clean-contaminated procedure and a prophylactic antibiotic should be administered prior to incision. We commonly use a first- or second-generation cephalosporin.


Surgical Management



  • The most common indications for trachelectomy are pelvic organ prolapse, pelvic mass, abnormal cytology, bleeding, and pain. Trachelectomy is a relatively safe and effective procedure. Patients should be counseled on the risk of bleeding and injury to the urinary tract or bowel.


Positioning



  • Positioning for a vaginal trachelectomy is similar to positioning for a vaginal hysterectomy (see Chapter 8.5, Vaginal Hysterectomy). The patient is placed in the dorsal lithotomy position using candy cane or Allen stirrups. The use of Allen stirrups is preferred in cases where there is a high likelihood of converting to an abdominal procedure or if there is a need for concomitant laparoscopy.


  • Positioning for a laparoscopic/robotic trachelectomy is similar to the positioning for a laparoscopic/robotic hysterectomy. The patient is positioned in the dorsal lithotomy position using Allen stirrups with the patient’s arms secured to her sides (see chapter on Diagnostic Laparoscopy, Patient Positioning).


Approach



  • An abdominal (open, laparoscopic, or robotic) approach is preferred when the patient complains of pelvic pain or endometriosis is suspected. In addition, if a pelvic mass is appreciated on examination or imaging, an abdominal approach is mandatory.


  • A vaginal approach is preferred in patients with significant comorbidities, when abdominal exploration is not required or when the trachelectomy is performed due to prolapse.
